Experts describe maker education as activities relating to the construction of artifacts that encourage learning through teamwork, problem-solving, and innovation. Teachers in recent years have been turning to maker-centered learning strategies to develop 21st century skills along with emphasizing strong content knowledge focusing on creation and creativity. Previous maker-based learning research focused primarily on the technology and tools associated with these activities; however, little research exists on the teachers'€™ involvement with these learning strategies. The purpose of this phenomenological study was to explore the experiences of teachers currently using maker-centered learning strategies as an instructional practice in grade 5-12 classrooms. Based on the idea of constructing knowledge through active learning, the conceptual framework for this research encompasses multiple learning theories including constructionism, constructivism, experiential learning, and cooperative learning. The research examined the motivation of teachers' using maker-centered learning strategies and the challenges and benefits they have experienced. Data were collected using semistructured interviews and written lived experience descriptions from seven teachers currently using maker-based learning in their classrooms and analyzed using InVivo coding. The participants described their experiences as facilitators in student-centered classrooms that focus on collaboration and learning through failure. Time and assessment are common challenges while increased student engagement and student social and academic growth are common benefits. Experts maintain that maker-centered learning improves 21st century skills and prepares students for success in college, careers, and lifelong learning opportunities.

Mobile technologies now afford unprecedented opportunities, resources, and possibilities for learning. Among them, is the opportunity for students to engage in hands-on, out-of-classroom learning activities such as Adventure Learning. Since 2007, Adventure Learning has developed as an educational framework for using information and communication technologies to connect learners with expeditionary teams where video-based communication provides a sense of adventure for learners. The study was conducted in a public high school where an Environmental Science teacher used mobile learning technologies to create Adventure Learning projects where students participated both fin the classroom and as members of an “expeditionary team.” It was also intended to examine both the benefits and challenges in implementing ubiquitous mobile technologies in the field, combined with the use of student-centered pedagogies in their classrooms. The major questions of the study asked how did a teacher leverage mobilized Adventure Learning to design learning activities? And how did active participation in a mobilized Adventure Learning project affect student interest in the subject of Environmental Science? The study involved examining the ways the teacher leveraged the affordances of mobile technologies to create a hands-on, collaborative, and Adventure Learning environments outside of the classroom. The hands-on learning activities were designed to enable students to gather first-hand information related to environmental science. Subjects in the study included a high school Environmental Science teacher along with 104 participating students. Using a mixed methods approach, qualitative data were gathered through observations of learning activities, interviews and focus groups and artifacts. Quantitative data were gathered through surveys administered to the students before and after the treatment. The results indicated that, contrary to the teacher’s expectations, students indicated a preference for learning through book and lecture rather than hands-on discovery of information in both pre and post treatment surveys. Results of the study also demonstrated differences in learning preference relating to percentage of students participating in field-based, hands-on learning activities or in lecture-book classroom learning activities. Recommendations for future research and for educational practice are offered. Limitations of the study include the small sample size and short time duration of the study. / text

Master of Science / Department of Mechanical and Nuclear Engineering / Bruce Babin / To keep students engaged in the learning process, educational engineering institutions need to enhance their curricula. Courses within an undergraduate curriculum need to be connected in a way that is meaningful and promotes student engagement through hands-on learning. Courses are currently designed like silos of knowledge with no connection between them, yet, there needs to be a realistic and practical tie between them. Prior research that addresses course integration, hands-on learning and student engagement has guided the development of this thesis. Building on prior research, a Fundamental Learning Integration Platform (FLIP) has been developed that uses a physical object to integrate traditionally mechanical engineering taught courses with the use of a single ubiquitous object. This learning platform has three desired outcomes: 1) it connects the entire curriculum, 2) it creates a physical connection between theoretical and practical engineering concepts, and 3) it engages and includes every student in the learning process. After identifying research to guide the development of the FLIP as well as identifying courses in a mechanical engineering curriculum, a desktop steam engine was developed and is shown that it is applicable to each course. This physical object acts as the FLIP. Ultimately, it will create a physical connection between theoretical and practical engineering concepts while integrating courses together and actively engaging each student in the learning process. Utilizing the same assessment methods used in the identified research, higher retention rates, increased passing rates of the Fundamentals of Engineering exam, and increased student inclusion in the classroom are all desired measurables of the FLIP. The results of this research have provided a well-developed FLIP that utilizes a physical object to increase student engagement while integrating traditional mechanical engineering courses together.

Doctor of Philosophy / Department of Agronomy / Johanna A. Dille / This dissertation has two complementary components: educational, in a survey of students in Weed Science and their perception of the Kansas State University Agronomy Learning farm, and research, regarding interactions between mesotrione and sulfonylurea herbicides. The Learning Farm serves as a resource where undergraduate students at KSU can develop agronomic skills through hands-on field site experiences and investigations. Students’ perceptions of experiential learning activities in the development of problem-solving and critical thinking skills were studied as a result of the Learning Farm. Activities included: undergraduate students in Weed Science (AGRON 330) developing a weed management recommendation, and Undergraduate Research Assistants (URAs) conducting weed science research projects at the Learning Farm. Students stated that experiential learning activities increased their critical thinking skills, required effective time management, and presented concepts that could be used in other situations. Pre- and post-project evaluation questionnaires showed that URAs had an increased interest in agronomy, weed science, and research following the completion of their project. For the research project, field and greenhouse studies were conducted from 2003 to 2006 to evaluate the efficacy of various sulfonylurea herbicides when applied with mesotrione or mesotrione + atrazine. Research demonstrated that the addition of mesotrione to sulfonylurea herbicides decreased efficacy of sulfonylurea herbicides on green foxtail, yellow foxtail, and shattercane. The addition of atrazine to the tank mix, or increased mesotrione rates, resulted in additional decrease in sulfonylurea herbicide efficacy on shattercane and foxtail species. Additional studies were performed to determine if absorption, translocation, or metabolism was the basis for the reduction in sulfonylurea herbicide efficacy when mixed with mesotrione or mesotrione + atrazine. Results indicated that the cause of antagonistic interaction between mesotrione and sulfonylurea herbicides in green and yellow foxtail was reduced absorption and translocation of the sulfonylurea herbicides. Producers who choose to apply mesotrione and sulfonylurea herbicides to corn should apply the herbicides sequentially to achieve maximum control of weedy grass species.

The purpose of this study was to determine how the Hahn Horticulture Garden at Virginia Tech can best focus their outreach efforts to benefit the local public school community. The study assessed the needs of local science teachers and how their needs can be met through educational outreach programs. A self-administered online survey was used to inquire about the use of experiential teaching methods using school gardens and other outdoor environments. The survey was also intended to determine interest in incorporating supplemental programs into the K-5 Montgomery County Public School curriculum to enhance the Virginia Standards of Learning related to plants and environmental science. The survey was sent to 273 K-5 teachers in the Montgomery County Public School System in Virginia. Because of the small number of responses, the results from the survey were not representative of the population, but were satisfactory to gain practical information for this study. Data analysis indicated existing programs, the need for programs, and how programs can best be implemented. Existing programs consisted of hands-on activities in the classroom including growing plants from seeds and dissecting and observing plant parts. Experiential learning opportunities outside of the classroom included school gardening, observations on the school grounds, and outdoor field trips. Survey respondents indicated a need for supplemental programs related to plants and environmental science. Teachers reported interest in a school gardening program, having a guest speaker in the classroom, receiving curriculum support, and taking their class on a field trip to the Hahn Horticulture Garden at Virginia Tech. Most teachers also showed interest in receiving in-service training to strengthen their knowledge of plants and environmental science. Based on the results of the study, there is a need for supplemental programs related to plants and environmental science. Engaging lessons should be developed to assist teachers with school gardening programs. Experiential learning opportunities such as meaningful field trips should also be developed. Other methods to supplement school curriculum include providing teachers with curriculum materials and lesson kits. All programs developed should correlate to the state-mandated standards. / Master of Science

Learning-by-doing learning environments support a wealth of physical engagement in activities. However, there is also a lot of variability in what participants learn in each enactment of these types of environments. Therefore, it is not always clear how participants are learning in these environments. In order to design technologies to support learning in these environments, we must have a greater understanding of how participants engage in learning activities, their goals for their engagement, and the types of help they need to cognitively engage in learning activities. To gain a greater understanding of participant engagement and factors and circumstances that promote and inhibit engagement, this dissertation explores and answers several questions: What are the types of interactions and experiences that promote and /or inhibit learning and engagement in learning-by-doing learning environments? What are the types of configurations that afford or inhibit these interactions and experiences in learning-by-doing learning environments? I explore answers to these questions through the context of two enactments of Kitchen Science Investigators (KSI), a learning-by-doing learning environment where middle-school aged children learn science through cooking from customizing recipes to their own taste and texture preferences. In small groups, they investigate effects of ingredients through the design of cooking and science experiments, through which they experience and learn about chemical, biological, and physical science phenomena and concepts (Clegg, Gardner, Williams,&Kolodner, 2006). The research reported in this dissertation sheds light on the different ways participant engagement promotes and/or inhibits cognitive engagement in by learning-by-doing learning environments through two case studies. It also provides detailed descriptions of the circumstances (social, material, and physical configurations) that promote and/or inhibit participant engagement in these learning environments through cross-case analyses of these cases. Finally, it offers suggestions about structuring activities, selecting materials and resources, and designing facilitation and software-realized scaffolding in the design of these types of learning environments. These design implications focus on affording participant engagement in science content and practices learning. Overall, the case studies, cross-case analyses, and empirically-based design implications begin to bridge the gap between theory and practice in the design and implementation of these learning environments. This is demonstrated by providing detailed and explanatory examples and factors that affect how participants take up the affordances of the learning opportunities designed into these learning environments.

Praktiska metoder/hands-on learning är en undervisningsmetod som har blivit mer aktuell i dagens undervisning. Ett av skolans viktigaste uppdrag är att det finns en koppling mellan undervisningen och världen utanför, vilket gör att undervisningen bör innehålla undersökande och experimenterande uppgifter för att främja nytänkande (Lgr 11 rev. 2019). Detta innebär en omvandling av den traditionella utbildningsmodellen till en som drar nytta av elevernas naturliga benägenhet att lära sig. Denna kunskapsöversikt syftar till att analysera och sammanställa forskning som belyser vikten av praktiska metoder/hands-on learning inom de naturorienterande ämnena samt till att analysera hur begreppet definieras. Vidare undersöks om praktiska metoder kan påverka elevernas motivation och förståelse av undervisningen. Urvalet samlades in via systematiska sökningar i databasen Eric (ProQuest), konsultation och manuell sökning. Utifrån förvalda urvalskriterier valdes totalt nio publikationer ut som besvarar kunskapsöversiktens syfte och frågeställningar. Kunskapsöversikten grundar sig i följande frågeställningar: Vad kännetecknar forskningen om praktiska metoder/hands-on learning inom grundskolans naturorienterande ämnen? Hur definierar forskningen praktiska metoder/handson learning? Vad i praktiska metoder/hands-on learning tyder på att elevernas motivation och förståelse utvecklas? I majoriteten av kunskapsöversiktens artiklar framkommer att praktiska metoder/hands-on learning ses som en framgångsrik undervisningsmetod för såväl elevernas lärande som motivation i de naturorienterande ämnena. Forskningen visar att praktiska metoder bidrar positivt till bland annat kunskapsinlärning, attityder och engagemang i undervisning. Flertalet beskrivningar som ges av begreppet praktiska metoder/hands-on learning handlar om att eleverna ska genomföra olika undersökningar och aktiviteter, vilket syftar till att ha en direkt interaktion med olika naturvetenskapliga fenomen. Motsatsen till praktiska metoder/hands-on learning beskrivs i vissa artiklar som undervisning som präglas av bland annat läroböcker, demonstrationer samt muntliga och skriftliga uppgifter där eleverna främst ska memorera fakta.

Organizational leaders use lean training as a process improvement strategy to eliminate waste and inefficiencies in processes. Of the 91% of company leaders who believed lean training was important, 64% of those leaders expressed the perception that workers do not comprehend lean training and methodology. The purpose of this qualitative single case study was to explore how healthcare managers successfully implemented lean training strategies to combat escalating costs. The target population consisted of healthcare managers in a single rural care hospital located in Tennessee who had implemented lean training strategies to train staff in lean principles and lean tools. The conceptual framework for this study was the general systems theory. Data were collected through semistructured interviews with healthcare managers, document review of public hospital data, and public quality reports. Member checking of interview data was used to strengthen the credibility of the findings. Yin's 5-phase qualitative data analysis process was used consisting of compiling the data, disassembling the data, reassembling the data, interpreting the data, and concluding the data. Themes emerged resulting from the use of methodological triangulation of collected data to include improving quality of patient care, teamwork and collaboration, hands-on learning, and training the trainers. The application of the findings may contribute to social change by identifying strategies related to lean training to address inefficiencies, improve quality patient care, and provide a safer healthcare environment.

Cyber-Physical Systems (CPSes) form the core of Industrial Control Systems (ICS) and critical infrastructures. These systems use computers to control and monitor physical processes in many critical industries including aviation, industrial automation, transportation, communications, waste treatment, and power systems. Increasingly, these systems are connected with corporate networks and the Internet, making them susceptible to risks similar to traditional computing systems experiencing cyber-attacks on a conventional IT network. Furthermore, recent attacks like the Stuxnet worm have demonstrated the weaknesses of CPS security, which has gained much attention in the research community to develop more effective security mechanisms. While this remains an important topic of research, often CPS security is not given much attention in undergraduate programs. There can be a significant disconnect between control system engineers with CPS engineering skills and network engineers with an IT background. This thesis describes hands-on courseware to help students bridge this gap. This courseware incorporates cyber-physical security concepts into effective learning modules that highlight real-world technical issues. A modular learning approach helps students understand CPS architectures and their vulnerabilities to cyber-attacks via experiential learning, and acquire practical skills through actively participating in the hands-on exercises. The ultimate goal of these lab modules is to show how an adversary would break into a conventional CPS system by exploiting various network protocols and security measures implemented in the system. A mock testbed environment is created using commercial-off-the-shelf hardware to address the unique aspects of a CPS, and serve as a cybersecurity trainer for students from control system or IT backgrounds. The modular nature of this courseware, which uses an economical and easily replicable hardware testbed, make this experience uniquely available as an adjunct to a conventional embedded system, control system design, or cybersecurity courses. To assess the impact of this courseware, an evaluation survey is developed to measure the understanding of the unique aspects of CPS security addressed. These modules leverage the existing academic subjects, help students understand the sequence of steps taken by adversaries, and serve to bridge theory and practice. / Master of Science
